M: Julia, this is Stephen, our new reporter. Would you have some time today to show him around? You know introducing him to the others makes him feel at home.
W: I’ll be happy to. Then after lunch I can set up his desk so he can get to work.
Q: What will Stephen probably do after lunch?

M: We’re going to have a dancing party for Mary tomorrow night. Would you like to join us, Jessica?
W: No, I’m afraid not. I have an appointment with my dentist then.
